Hmmmm I've tried the 1_download_assets again and it seems to run through the entire thing without pausing to install more files so maybe I might have to delete and redownload the files for the mech beasts?
Let's compare config.ini files. It gets created by the 3_write_config script. You could try backing up your config.ini (cutting and pasting it somewhere else) and put my config.ini where it was (same folder as the scripts). Then run the player and click one of the new character scenes, if any appear.
Edit: I had to split the file into fewer than 6 parts that are less than 97KB each. Then I renamed "config.zip.001", "config.zip.002", "config.zip.003", and "config.zip.004" to "config 001.zip", "config 002.zip", "config 003.zip", and "config 004.zip" since 001, 002, 003, and 004 aren't recognized filetypes.
